In many instances, the whistling noise is produced by vents that aren’t properly attached or the incorrect size. In the winter months, the whistling noise may be reduced by slowing down the system’s fan speed. This will slow the speed of air moving through the system and may help eliminate the issue.
It could be the sound of refrigerant gas in your expansion valve, for example. But a persistent hissing or whistling sound could be a sign of a refrigerant leak. A refrigerant leak could occur in your refrigerant lines or in your internal valve.
This high-pitched sound is typically the sign of low return airflow. In other words, your system’s blower is “starved for air.” It’s trying to pull in a certain amount of air, but is struggling to do so. As this happens pressure and velocity increases, therefore increasing the sound level (that’s the sound you hear).
Why is my car making a high-pitched whistling noise?
A high-pitched, shrill whistle can really get annoying, especially if it occurs frequently while you drive. There are generally two possible explanations for the whistle.
